PxP vs IPU (mix 2 RGBA and convert to I420 or NV12)

[Kanstantsin]

Hi there. 

I want to blit to images the same format and sizes (RGBA 1024x768), then the images should be convert to I420 or NV12 (to send to VPU) on 60 fps.

I know I can do it with IPU, but I wonder if I can do it with PxP. Does PxP have any advanteges  over IPU.
It important to me to get  low power consumption and low delay.

Hi Kanstantsin

some pxp examples can be found in unit tests

https://source.codeaurora.org/external/imx/imx-test/tree/test?h=imx_5.4.70_2.3.0

I am afraid PxP has not any advantages over IPU.

Hi Igor. 

May be IPU has advanteges over PxP?

[Kanstantsin]

It seems to me them are both can the same at this context. We can send some operaton to PxP instead of IPU if you see that the IPU is overloaded by other tasks.
@igorpadykov I'm right?
